Pine tar is a thick, sticky liquid substance made from burning pinewood. Hitters are allowed to use on bats to get a better grip. Rules prohibit pitchers from using it, but according to a slate.com report, people in baseball consider pitchers using pine tar a minor offense. In a 2005 column in the Sporting News pitcher Todd Jones said he used pine tar every time he pitched a home game with the Colorado Rockies, "Pine tar is no big deal to players," Jones wrote. "Everybody uses pine tar. … It's almost a basic part of the game. Sandpaper and Vaseline, however, are looked at as cheating."
